SPECIFICATION forming part of Letters Patent No. 665,092, dated January 1, 1901.

Application filed September 17, 1900. b'erial No. 30,228. (No model.)

To all whom it may concern.-

Be it known that we, MAX W. HENIUS and JOHN HERROLD, citizens of the United States, and residents of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Machines for Assembling Corset Eyes and Rivets and Conveying and Riveting Them, of which the following is a specification.

This invention relates to an improvement in machines for assembling eyes and rivets, and after they have been assembled feeding them to a predetermined point.

Our invention further relates to an improvement in machines for assembling eyes and rivets and then feeding them to a predetermined point in such a manner that they may be rapidly and efficiently riveted to the corset-steel.

A practical embodiment of our invention is represented in the accompanying drawings, in which- Figure 1 represents our improved machine -in front elevation. Fig. 2 is a top plan view of the same. Fig. 3 is a partial top plan View, certain of the parts being broken away to more clearly show the parts beneath them. Fig. 4 is a side view ofthe machine, certain portions of the same being broken away to more clearly show the interior construction thereof. Fig. 5 is a partial vertical section taken from front to rear through the base of the machine to show more clearly the means for feeding the eyes into position to receive the rivets and then advance them into the delivery-wheel. Fig. 6 is an enlarged detail vertical section taken from front to rear through a portion of the machine to show more clearly the means for assembling the rivets and eyes. Fig. 6 is a detail transverse section taken on the line 6 6 of Fig. 6. Fig. 7 is a front view of the same. Fig. 8 is a detail reverse sectional view on the same scale as Figs. 1 to 5, inclusive, showing the manner of controlling the feeding of the rivets to the eyes. Fig. 9 is a detail view, on an enlarged scale, showing the manner of engaging the corset-steel with the eye preparatory to withdrawing the eye from the delivery-wheel. Fig. 10 is another detail view, on an enlarged scale, showing the eye and corset-steel withdrawn from the Wheel and placed in position upon the anvil ready to have the eye secured permanently to the steel by upsetting the ends of the rivets. Fig. 11 represents a front view of the pair of reciprocating boxes at the lower ends of the chutes, showing more clearly the spring-actuated arms for temporarily retaining the lowermost pair of rivets in the chutes until they are positively withdrawn after they have been engaged by the eye. Fig. 12 is a vertical section through one of the boxes in the plane of the chute therein, and Fig. 13 is an inverted plan view of the said boxes.

The base of the machine is denoted by A', and uprising from the rear thereof are suitable posts a a, in which is rotatably mounted the main drive-shaft B.

The base A is provided at its front with a centrally-arranged post a which forms a sup- 7o port for the riveting-anvil O. This anvil C is provided with a-lateral extension 0, serv'-' ing as a restfor the corset-steel when the eye is being riveted thereto. This lateral extension 0 is made of harder material than the balance of the anvil, and it may be shifted longitudinally thereon to present a new surface for the hammer of the riveting device to'\ strike when one portion becomes too much worn. This anvil is further provided with a projection c, uprising therefrom, which is arranged to enter the slotv in the eye to properly locate the eye and steel with respect to the hammer and anvil while the eye is being riveted to the steel. The baseAis further provided at points intermediate its front and rear with a pair of posts or stanchions a at, in which is rotatably mounted the deliverywheel shaft D, to which is imparted an intermittent rotary motion in one direction from the main drive-shaft in a manner to be hereinafter set forth. The base A is further provided at points intermediate the pair of posts a a and the pair of posts a a with a pair of posts 01. a which form supports for the bed- 5 plate E, onto which are fed the eyes F and rivets G in the manner to be hereinafter described.

A rivet-reservoir-supporting frame H uprises from the base A, and there is mounted to rotate in its top a main rivet-supply reservoir I, the shaft 11 of which has fixed thereto a suitable driving-pulley 2'', which may be driven at the required speed by a belt. (Not shown herein.) This reservoir may be supplied With rivets through an opening normally closed by the stopper The reservoir I is preferably of closed hollow cylindrical form, and it is provided through its periphery with one or more pairs of exit-holes 2' through which the rivets are permitted to escape when the pair of holes is at its lowermost point during the rotation of the reservoir.

A pair of troughs J J is hinged on a cross shaft h, supported by arms h 7L2, projecting from the frame H, the upper ends of the said troughs J J projecting beneath and to the rear of the rivet-reservoir in line with the holes i the said troughs being further provided with branches J J which extend beneath and to the front of the rivet-reservoir in line with the holes 71 An overflow-rivet reservoir K is carried by the frame H, into which reservoir project the lower ends of the hinged pair of troughs J J. The bottoms of the troughs are open fora distance to permit incomplete rivets to fall therethrough into the reservoir K, so as not to impede the alining of the perfectly-formed rivets.

A pair of rivet-chutes L L extends downwardly from the overflow-reservoir K, where the chutes are connected with their respective troughs J J for receiving the rivets as they slide from the said troughs.

The construction of the lower ends of the troughs J J is such that as the rivets slide from the upper portions of the said troughs certain of the rivets will travel along the narrowed lower ends of the troughs, with their shanks within the lower ends of the troughs and their heads exterior to the same. If the rivets should not be fed in this manner, the upper ends of the chutes are so formed that they will force the said rivets out of the way,so as to insure the proper feeding of all the rivets which remain down the chutes. The overflow-reservoir K will receive the surplus rivets which are not engaged by the lower ends of the said troughs. As the rivets slide along down the lower ends of the troughs J J their heads are caused to enter the interiors of the chutes L L, while their shanks or stems project rearwardly therefrom through the open slots in the backs of the said chutes. These chutes L L extend downwardly through the interior of vertically-reciproeating boxes L L the lower ends of which boxes are in close proximity to the top of the bed-plate E of the machine, where the said chutes are curved toward the front, so as to present the bottom two rivets at substantially right angles to the face of the bed-plate. A vertically-reciproeating movement is imparted to the chutes L L, so as to agitate the rivets and cause them to positively feed down the chutes in a manner to be hereinafter described.

A reservoir M for the eyes F is located immediately to the rear of the lower ends of the chutes L L, which reservoir has an open lower end for permitting the escape of the bottom eye of the stack along the bed-plate E.. The eyes may be fed to the reservoir through a chute m, which leads from a point near the top of the reservoir upwardly and rearwardly to the frame 11, where it may be suitably supported, in the present instance by a cross-bar 7L3. This reservoir M for the eyes is formed in a supporting-block M, uprising from the bed-plate E, accees to the interior of the reservoir M being obtained at any time by means of a removable back m, which has a sliding engagement with the block M. This block M also serves to guide the rivet-chutes L L and their attached boxes L L in their vertically-reeiprocating movements, as will hereinafter more fully appear.

A delivery-wheel d is mounted on the shaft D in the space between the anvil C and the bed-plate E, and it is keyed to rotate with the said shaft. This delivery-wheel is provided on its periphery with a series of teeth cl and slots (1 extended inwardly from the face of the said teeth for receiving the eyes, with the rivets therein, from the bed-plate E and conveying the eyes and rivets, as the wheel is rotated around step by step, into position to be withdrawn when brought into proximity to the anvil O, the said assembled eyes and rivets beingpresented to the anvil with the rivet-shanks projecting upwardlyin position to enter corresponding holes in the corsetsteel. The eyes F are inserted into the periphery of the wheel a suflicient distance to cause the heads of the rivets to engage the face of the teeth, so thatthe rivets will not fall out as they are being brought down to the anvil O. The delivery-wheel shaft 1) is further provided with a ratchetwheel (1 keyed thereto, which ratchet-wheel is engaged by a pawl (1 carried on the free end of one arm of a rocking lever N, which is hinged at n to one of the supports of the bedplate E, in the present instance the support a, the end of the other arm of the lever N being engaged by the delivery-wheel-operating cam 1), fixed to the rotary shaft B. The delivery-wheel is yieldingly held stationary While the pawl d is returned into position to impart the next movement in a forward direction to the wheel by providing one face of the delivery-wheel with an annular series of depressions (1 corresponding in number to the teeth on the wheel, which depressions are successively engaged by the free end of a spring-arm d secured to the support a of the anvil O.

The hammer for riveting the eyes to the steels is denoted by O and is shown as developed into two rearwardly-extended branches 0 0, engaged by corresponding cams 7) b fixed to rotate with the shaft 13. This hammer is hinged on the delivery-wheel shaft D, the front end of the hammer having secured therein the head 0 ITO The following means are employed for feeding the eyes one by one from the reservoir M, first, into position to receive the rivets, and, second, to advance the eyes, with the rivets therein, into engagement with the delivery-wheel: The bed-plate E is provided with a shallow groove 2, which extends from the front of the bed-plate along its top rearwardly to the back of the same and centrally of the bed-plate. This bed-plate is further provided with a pair of deeper grooves e e extended inwardly from its front to a point just to the rear of the delivery ends of the chutes L L and in alinement with the said delivery ends of the chutes. The groove sis of sufficient width to permit the reception therein of the bottom one of the stack of eyes F. A slide P is fitted to reciprocate on the bedplate Ein the present instance by dovetailing the top of the bed-plate into the bottom of the slide. This slide F is provided with an eye-feeding tongue 1), fitted to reciprocate in the groove 6. The slide is positively forced forward by means of a cam b fixed to the shaft B, and is returned to its normal rearward position by means of a retracting-spring 19, one end of which is secured to the slide P and the other end to a pin a uprising from the base A. To prevent the jarring of the machine by the return movement of the slide under spring tension,we provide a pneumatic cushion, the cylinder 19 of which is supported at the side of the bed-plate and the plunger 19 of which is secured to the slide. I

The means employed for properly delivering the rivets to the eyes are arranged and constructed as follows: The block M is provided with a front plate Q, which serves to retain the vertical reciprocating boxes L L in position therein, and in the said front plate we mount a pair of vertically-reciprocating bars Z Z, which are held in position by upper and lower straps q q. These bars Z Z are yieldingly connected at their upper ends to the boxes L L respectively, by means of collars Z Z which surround pinsZ" Z screwed into the tops of the said boxes. Coil-springs Z Z are interposed between the heads of the pins Z Z and the collars Z Z, and loose leaves Z Z embrace the pins Z Z and are interposed between the-tops of the boxes L L and the collars Z Z The upward movement of the boxes, and thereby the chutes, is limited by means of adjusting-screws Z Z which bear against the heads of the pins Z Z. The boxes are held normally at the limit of their down ward movement by means of retraction-springs Z 1 having their upper ends engaged with the collars Z Z and their lower ends engaged with the front plate Q of the block M. Adj ustingscrews Z Z pass through the collars Z Z and are arranged to accurately adjust the limits away from engagement with the same after they have been fed into their holes in the eye which has been moved into position beneath them by the following means: The bars Z Z are provided with outwardly-projecting pins Z Z which are engaged by a rocking lever B, hinged at r to a lateral extension q of the front plate Q, the free end of the said lever being operated by a rocking lever S, hinged at s at the side of the bed-plate E, which rocking lever is operated by a cam b, fixed to rotate with the camshaft B. A keeper g serves to hold the free end of the rocking lever Rin position in close proximity-to the face of the front plate Q. This rocking lever B is accurately adjusted with respect to the rocking lever S by means of an adj listing-screw r, the lower end of which rests directly upon the forwardly-extended arm of the said lever S. This rocking lever B is further provided with a downwardlyextended arm 0, which is arranged to engage the face of the eye F when the eye has been fed into position to receive the lowermost pair of rivets and when the lever R is at the limit of its downward movement, so as to steady the said eye, while its forward movement is temporarily arrested to receive the said pair of rivets. The nextsucceeding pair of rivets is temporarily prevented from dropping down into position to enter the next succeeding eye by devices carried by the bars ZZ. As these devices are quite similar one only is shown viz., the one attached to the bar Z. Near the lower end of the bar Z and projected inwardly therefrom we provide a hollow lug T, from which a pin t extends downwardly into position to engage the head of the rivet next succeeding the bottom one. This pin 25 has a limited sliding movement in the lngT and isv rivet held thereby to drop into position to be fed to the next succeeding eye. The lowermost pair of rivets are held yieldingly in position by means of a pair of spring-actuated sliding arms 4) '0, mounted on the bottoms of the boxes L L with their inner ends projected partially across the mouths of the chutes in the said boxes. The inner ends of This pin tis so arranged that it will still the said arms 11 '0 are beveled, as clearly shown in Fig. 13, so as to permit the lowermost pair of rivets to be positively drawn from the chutes after the rivets have been engaged with the eye.

An automatic alarm is provided for notify ing the operator if from any cause the bottom eye of the stack should become cram ped and not be fed by the slide P into position beneath the rivets. The alarm is operated by the following mechanism: A sliding plate U.

is mounted in the block M at the front of the reservoir M and extends from a point a slight distance above the top of the block to a point in close proximity to the top of the bed-plate E. This plate U is supported in this position by a spring-arm 'Lt, projecting from a plate it, fastened to and insulated from the top of the block M. A contact-plate u is secured to the top of the block M and projects over and is spaced a slight distance above the top of the Vertically-sliding plate U. Wires M3 11, lead through a battery n and bell a so that when the plate U is raised into engagement with the contact-plate M2 an electrical circuit is formed, thus ringing the bell a. If the bottom eye of the stack is bent or becomes cramped, it will force this vertically-sliding plate U upwardly and complete the circuit above described, thus warning the operator, who may stop the machine in any well-known manner (not shown herein) until the cause of stoppage is removed.

The operation of our invention is as follows: The rivets are fed into the rivet-reservoir I and the eyes are fed into the reservoir M. After the rivets have been fed from the reservoir downwardly through the rocking troughs .I J and into the chutes L L the practical operation of the machine is begun. The eyes are advanced one by one into position beneath the lower end of the chute, Where each eye is stopped momentarily and a pair of rivets engaged therewith. The eyes are again advanced, drawing the rivets from the chutes, and fed forwardly into engagement with the delivery-wheel d, which wheel brings them around step by step into proximity to the anvil C, with the shanks of the rivets projecting upwardly. The operator causes the steel to engage one of the eyes by pressing the holes in the steel over the shanks of the rivets in thee'ye. The eye is then withdrawn from the delivery-wheel by moving the steel a slight distance forwardly until the projection 0 on the face of the anvil enters the hole in the eye, thus centering the rivets with respect to the hammer. The hammer is then depressed and completes the operation of securing the eye to the steel.

By the use of this machine the riveting of the eyes to the steels is materially simplified and is done in a much more rapid and efficient manner than has hitherto been possible.

It is evident that changes might be resorted to in the form, construction, and arrangement of the several parts without departing from the spirit and scope of our invention. Hence we do not wish to limit ourselves strictly to the structure herein set forth; but
